Ultra steep spectrum radio sources in the lockman hole: Servs identifications and redshift distribution at the faintest radio fluXES
Ultra steep spectrum (USS) radio sources have been successfully used to select powerful radio sources at high redshifts (z ~>2). Typically restricted to large-sky surveys and relatively bright radio flux densities, it has gradually become possible to extend the USS search to sub-mJy levels, thank...
